Kakeru enters the soccer club as a provisional member, just as the letter says. When the topic of lunches comes up after practice, Kakeru jokingly asks Naho to make lunch for him as well. Naho finds herself bewildered by his words, but feels pushed to act by the letter from herself 10 years in the future, which tells Naho that she wishes she had made lunch for Kakeru.
Now, ten years in your future, 
Kakeru is no longer with us.
،الآن، عشر سنواتٍ في مستقبلك
.لم يعد كاكيرو معنا
Stimmt aber.
10 años en tu futuro, Kakeru ya no está.
10 años en tu futuro, Kakeru ya no está.
Ora, 10 anni nel futuro, Kakeru non c'è più.
Nesse momento, daqui dez anos,
o Kakeru não está mais aqui.
Сейчас, десять лет спустя, Какэру 
больше нет с нами.
